How can I take a boat that can cross the ocean of birth and death?

When a monk asked Master Sulbong, “How can I take a boat that can cross the ocean of birth and death?”, the master answered, “If you get on a raft, it will sink to the bottom, and if you get on a boat, it will sink, too.”

Student: “Why do a raft and a boat sink whenever we board them?”

Master: “Because no vehicle is large enough to accommodate you.”

Student: “Then, how can I cross the ocean?”

Master: “Why don’t you jump over it?”
